tions or fingers l1 .and thelattem with the stock 4f 9, are forceddownwardly togethers and as the maximum pressure is exerted `on Y .y95vv In.k associating the parts kofthel brush `the* the projections orfingers and the latter engage the upper' side of the annulus 15 the saidannulus will be tightly held and all crevices will be closed. In swagingthe flange 8 inwardly care will be taken to avoid the formation ofshoulders or projections,

as shown by Fig. 2, or the upper side of the said flange and of theadjacent edge portion of the back 5 will be flush with the upper sidesof the projections or fingers 11. By thus carefully associating theparts of the brush an aseptic device of this character is provided,there being no crevices or openings or shoulders for the collection ofgerms or dirt at any point.

The brush consisting of the inner bristles 10 and outer surroundingrubber brush members or teeth 17 has been particularly devised for useas a combined cleansing and massaging brush, and in the use of thisbrush material benefits will accrue by reason of the fact that thebristles are shielded and prevented from having contact with the gums,the latter being engaged wholly by theyielding rubber brush lmembers orteeth 17 with a massaging effect, and by this means tender or soft gumswill be strengtlr ened and hardened and at the same time the bristles 10will be held upon the surface of the teeth for cleansing pur oses. Thebrush may be used either in right or left position with the sameadvantages. n

It is proposed to make the brush in various sizes and of differentshapes, both as to peripheral and surface contours, and in view of thecomparative simplicity of the brush embodying the cleansing andmassaging features the cost of manufacture is materially reduced,especially in view of the fact` that the brush elements are securedwithin the back by the simple swaging operation of the flange 8 inwardlyover the lprojections or fingers 11 and both parts of the brushelementsthereb simultaneously and accurately disposed within the back.

What is claimed is:

1. In a brush, the combination of a back, a stock carrying bristlemembers, and rubber brush members having a supporting base structurallyindependent of and held in the back by the stock and surrounding theperiphery of the bristle members, a part of the back being project-edinwardly and engaging the edge ofthe stock to secure the bristle andrubberv members in place.

2. In a brush, the combination of a back, a stock disposedin the backand carrying bristle members, and a rubber annulus carrying brushmembers surrounding the bristle members and having portions of the edgeof the stock extending over and bearv ing thereon. l

3. In a brush, the combination of a back having a seat therein, a stockcarrying bristle members and provided with peripheral outstandingprojections with spaces therebetween, and a rubber annulus surroundingthe stock beneath the projections and having brush members projectingthrough the spaces and surrounding the bristle members, the stock andannulus completely filling the seat of the back and secured by a portionof the. latter engaging the rojections.

4. In a brush, the com ination of a back having4 a seat therein, a stockcarrying bristle members, and a double row of rubber brush memberssurrounding the bristle members and having carrying means independent ofthe stock and over which portions of the stock extend within the seat.

5. In a brush, the combination of a back, a stock carrying bristlemembers, and a rubber annulus surrounding and located beneath the edgeportion of the stock and in.

terposed between the latter and the sides and ends of the `seat andhaving brush members extending upwardly through portions of the stockand completely surrounding the bristle members.

i 6. In a brush, the combination of a back having a seat therein with aiange surrounding the margin of the same, a stock disposed inthe seatand carrying bristle members, and a rubber annulus surrounding a portion.of the edge of the stock and having brush members projecting upwardlythrough the latter and completely surrounding the bristle members,portions of the stock projecting over the annulus andv having the flangeof the back bent inwardly thereagainst.

7. In a brush, the combination of a back having a seat therein with aflange sur-` rounding the margin thereof, a rigid stock having aplurality of projections surrounding the periphery thereof with spacestherebetween, the upper port-ions of the ends of the projections beingdownwardly beveled, and a rubber annulus surrounding the stock beneaththelproject-ions and having rubber brush members extending upwardlythrough the projections, the stock having bristle gmembers locatedwithin the rubber brush members, the stock and annulus being secured inthe back'by bending the ange of the latterv inwardly against the beveledends of the projections and forming a flush joint with the uppersurfaces of the said projections.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
